What is the relationship between botany and the Iceman?
It’s ethnobotany, or in this case because we are in the past it is palaeo-ethnobotany. Palaeo-ethnobotany deals with the relationship between plants and man in prehistory and history. Palaeo-ethnobotany teaches us about useful plants (nutrition, technical plants, etc.) evolution of crops, agricultural regimes and the molding of the cultural landscape.
